TOOL-HOLDER.

SPECIFICATION forming part of Letters Patent No. 361,155, dated April12, 18871 Application filed October 30, 1&86. Serial No. 217.553. (Nomodel.)

T at whom it may concern:

Be it known that we, WILLIAM FISH and Isaac DEETER, citizens of theUnited States, residing at Pleasant Hill, in the county of Miami andState of Ohio, have invented certain new and useful Improvementsin'Tool- Holders; and we do declare the following to be a full, clear,-and exact description of the invention,.such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

The invention will first be described in connection with the drawings,and then pointed out in the claims.

Figure 1 of the drawings is an elevation in perspective of ourtool-stock; Fig. 2, a transverse section, and Fig. 3 a group of detailviews. Fig. 4 is a perspective view of the rotating core.

In the drawings, A represents a shell or tube which has one or morelongitudinal slots, a, and, if preferred, the cross-slots a. The slots aare open at one end of tube where the bore is large, and closed at theend where the bore is small, comparatively, while the cross-slots a openinto the slot a. By this construction abit for drill or screwdriver Bmay be provided with a screw, 1), working in a transverse holesurrounded by a thread and kept always in place. It is entered at theopen end of slot (I, passed down until the bit protrudes to the desiredextent from the small hole, and then tightened to hold the bit fast. Bysimply loosening the screw the reverse operation of removing the bit isaccomplished. The shank of screw may be moved into the crossslots.

At the small end of tube A we use a countersinking-tool, O, which may beintegral therewith or screwed into position.

D is an end plug provided at one end with the round head d, having aset-screw, d, which passes through slot or and clamps it to the tube,and at the other end it has a tapering head, (7?, which is not round,but of a preferably angular cross-section, and cross'notched at d toreceive the point of a clamp-screw, (1*,

which retains it in the hole 0 of anordinary the core any preferred bitmay be used, and

they may be changed in a few moments. when the core G is used,we makeone or more openings, a near the rear end, so that the core may be firstinserted in the tube and the bits or other tools then placed in thegrooves. some kinds of work it will be a great convenience to have ourrevolving core, while in others it will not be necessary.

Having thus described all that is necessary to a full understanding ofour invention, what we claim as new, and desire to protect by LettersPatent, is

1. The combination, with a handle, E, having the hole e and theset-screw (1*, of the plug D, having an end shaped to fit said hole eand provided with cross slots 01 to receive the end of said screw, asdescribed.

2. The combination, with a set-screw, d, and a tubular tool-stock openat both ends and provided with the longitudinal slot (1, of a plug, D,having a head fitting the upper hole of said stock, and having alongitudinal slot to receive the point of said screw, whereby the plugis held in the stock without being able to turn therein.

3. An open-ended tubular tool-stock having the longitudinal slot (1 andsuitable clampscrews, in combination with a core longitudinally groovedto receive different tools and adapted to turnin the stock, as and forthe purpose specified.

In testimony whereof we affix our signatures in presence of twowitnesses.
